  <title>CSS Pseudo-Elements Test: inheritance of selection highlight colors from its parent element</title>

  <meta name="assert" content="In this test, 'color' and 'background-color' have not been given a value for the span element. Since its parent element has an highlight pseudo-element, then these values should be inherited. Therefore the span element should be green on a yellow background and should not use the OS default selection highlight color values.">

  <!--
  When any supported property is not given a value by the
  cascade, its value is determined by inheritance from the
  corresponding highlight pseudo-element of its originating
  element's parent element (regardless of whether that property
  is an inherited property).

  <script>
  function startTest()
  {
  var targetRange = document.createRange();
  /* We first create an empty range */
  targetRange.selectNodeContents(document.getElementById("test"));
  /* Then we set the range boundaries to the children of div#test */
  window.getSelection().addRange(targetRange);
  /* Finally, we now select such range of content */
  }
  </script>

  <body onload="startTest();">

  <p>Test passes if "Text sample" is green and if its background color is yellow.

  <div id="test"><span>Text sample</span></div>
